Cables
There are a few rules you must observe when selecting the cables:
● The cables for the digital inputs must be shielded.
● The cables for the count signals must be shielded.
● You must apply the shields to the count signal cables both on the pulse encoder and in
close proximity to the module, e.g. via the shield application element.
● Cables A and /A, B and /B, N and /N of the incremental 5-V encoder must be twisted in
pairs.
The following figure shows details relating to the connection of incremental 5-V encoders.
